Mean and kernel functions for first and second derivatives #2235

ankushaggarwal · 2022-12-24T11:09:48Z

Added new classes to work with derivatives:

Second derivative RBF kernel called RBFKernelGradGrad (without mixed second derivatives)
Three new mean functions:
a. ConstantMeanGradGrad
b. LinearMeanGrad
c. LinearMeanGradGrad

…ested more rigorously.

…t and second (non-mixed) derivatives

This mostly looks good! Diag should be implemented though.

There are linting errors - can you make sure that you pass the precommit hooks (see our contribution guidelines in the readme).

Additionally, please make sure that you add this kernel and these means to the documentation, and be sure that the docs compile for you locally (without warnings).

Thanks @ankushaggarwal !

Thanks @gpleiss I have made hook fixes using pre-commit and added the new kernel and means to the doc files. However I cannot compile them locally (I am getting different errors, such as version.py not found etc.

I have implemented the diagonal option.

Would you mind splitting out the hook update into a separate PR? It's good practice and easier to figure out if things go wrong if this is not intermingled with feature additions.

@Balandat I am not too familiar with the hook updates. Do you mean the changes in .pre-commit-config.yaml or changes to all the files by pre-commit (in commit c18e6d8)

I'm not sure why we need to change the pre-commit-hooks file at all. Can we get rid of these changes?

Yes, removed it.

I have implemented the diag option for rbf_kernel_gradgrad

Thank you for adding the diag functionality, but this PR still needs unit tests. Please also add docstrings and type hints to all new classes and methods.
